Abstract

Preliminary results are presented for decays of the new resonances J/ψ and ψ' into final states containing photons. Neutral final states at √s = 3.1 GeV are discussed. There are arguments that the spin of the Pc state at 3.5 GeV is different from 0. Final states π+π-γγ at 3.1 GeV are analysed on a statistical basis.
